SBM Magnum Roller Rocker Arm Set - Shaft Mnt.

The SBM Magnum Roller Rocker Arm Set - Shaft Mnt. from COMP CAMS is an essential upgrade for high-performance engine builders and mechanics looking to enhance valve lift and improve valvetrain geometry. This set is particularly beneficial for those focused on reliability during sustained high RPM operation.

Shaft-mounted rocker arms provide precise transfer of cam lobe motion to pushrods, surpassing the performance of stock stamped rockers. The roller rockers utilize hardened roller bearings to reduce friction at the valve stem interface, which can lead to increased horsepower and improved fuel efficiency. This design also maintains precise rocker geometry, eliminating deflection common in stud-mounted arms.

The SBM Magnum configuration is compatible with small-block applications, ensuring efficient power transfer without extensive modifications. This roller rocker system is ideal for those assembling stroker engines or restoring performance classics, delivering consistent and repeatable valve actuation across the powerband.
